Re: New Retumbo Powder
I have new lots of Retumbo that are definitely different from an older lot., couple of years. Using my 6.5x284, the older lot would produce 2965 FPS with 59gr. Two different new lots produce 3015 fps with the same charge. It is consistently 50-60 FPS faster. No pressure signs, and my groups are just slightly larger, by .25MOA or a little less. Though it might be my chronograph, but the difference on the readings are consistant between the old and new lots.
